If this were a street car (like a pro-street) then a cowl would be more appropriate looking. However, you need to remember, this is an ALL OUT race car and it is functional.
As the car accelerates and the speed increases during the run, more air is force fed into the carburetor making more top end HP. We built an "air box" around the carburetor hat and finished it off with 2" thk foam where it meets the underside of the hood. The air has NO place to go but down the carb. Its good for about .10 of ET.
Besides, there are no cowl hoods in Pro-Stock either.
